So, can I say that measuring the mash pH at any time after the time used on the experiment that difined coefficients a, b, c and pHdi, the result will be approximately the same? Thanks, Fabiano da Mata

What you imagine that will happen If I do a Whirlpool in a vassel with inclined bottom? May trub concentrate to de lower side?

@WBARBER69, which pins of KY-040 should be linked to port 7, 8 and 9? Ground and + should be linked too? Thanks, Fabiano da Mata

@day_trippr, I think the easiest way will be buy a correct rotary encoder. What would be? Thanks, Fabiano da Mata

@CadiBrewer, dont worry about it. So, what is the recommended model rotary encoder to work properly with the board? Thanks Fabiano da Mata

@CadiBrewer, my rotary encoder is KY-040. There are 5 pins: CLK, DT, SW, + and GND. Where should I connect each one to be able to use rotary encoder as a input device? Or this encoder is not compatible? Thanks, Fabiano da Mata

@cadibrewer and @day_trippr, is this board version ready to receive Rotary encoder? Thanks, Fabiano da Mata

So, imagine a batch with 60 L of finished beer, the we have about 35 L of mash water plus 45 L of sparge water, and about 12 kg of barley malt. If all oxalate will precipitate as calcium oxalate, so I will need, only to precipitate the oxalate, 234 ppm of Calcium (see below). It is? -...

People, as I asked, after I reach mash pH, It still fixed until mash end?

@mabrungard, Is it correct to state that the pH at the end of mash would be the mash pH? In other words, after reaching the mash pH, that value that theoretically would be calculated by tools, would does not change any more? Or have we fix the time when we should measure it? Thanks, Fabiano da...

People, initialy we have calcium content given by water report and any other addiction. Some of calcium will precipitate with phosphates and neutralize same alkalinity. My doubt is how much calcium should stay remaining in ionic form in cold wort (after boil) to provide the minimum content to...

@RPIScotty, 2 suggestions: 1) create a place where you could upload versions, instead post every time you have new version. 2) Some users are more confortable with international unit system. Verify possibility to create a way of user select unit system. Thanks, Fabiano da Mata

What is the Rotary Encode function? How to link it to the board? Thanks, Fabiano

@ajdelange, Send me too. :)

@ajdelange, could you also send me a copy of the paper? Thks, Fabiano da Mata

@CadiBrewer, thanks for explanation. From the file attachad (P-fet), I have to link D (3) with S (2)? May I ommit also PNP transistor? PNP transistor do the same of P-fet (shut off LCD)? About LED, those have 2 poles. One pole should be linked to anode after resistor and the other should be...

@CadiBrewer, is it possible use your board without BSS84? What this component do? I am having difficult to find it in Brazil. Is there other name/reference for this component? Thanks, Fabiano

@daytrippr, thanks for you fast reply. About "to enable wireless Arduino agents" is used to connect Arduino to RPi/PC? And about "to allow programming at the Arduino" Could we programming Arduino w/o web interface? I didn´t undestand well how to for both questions, could you explain a little...

What is the reason to use Bluetooth attached to shield? And the Rotary encoder is used for what? About resistors, what is the best kind of? metalic, ceramic....? About resistors power, the value shown (ex 1/4W) this is the minimum power desired?

The original pH is 7.5.
